The V-DAC is a sensational state-of-the-art DAC. By any measurement its performance is way beyond so-called state-of-the-art competition.
In fact overall the technical performance of the V-DAC is probably about the best in the world regardless of price. There is no trickery here. It's simply that we use state-of-the-art digital components (these are very expensive) and implement them with state-of-the-art circuitry and layout. The secret is simple; there's no ridiculous packaging, and absolutely no wastage on anything. The V-DAC is rather like an F1 racing car. It is completely funcitonal with no excess flab or wastage anywhere.
